Hello everyone.
We are currently working on a wound summary for chronic wounds. These wounds might be a recurrent wound. We want to be able to link the current wound to an older wound for which we might add additional information like healing duration or procedures performed. We already figured out that we should add an id to the wound which we modeled as an act. Now we want link the act to another act using entryRelationship, but I am a little unsure about the typecode to use.
We had a look at https://www.hl7.org/documentcenter/public/standards/vocabulary/vocabulary_tables/infrastructure/vocabulary/vs_ActRelationshipType.html#x_ActRelationshipEntryRelationship, but I don't think that any of the proposed codes fits to our use case. When I had a look at the underlying code system (https://www.hl7.org/documentcenter/public/standards/vocabulary/vocabulary_tables/infrastructure/vocabulary/ActRelationshipType.html), I thought the code PREV would fit very well, but it is not part of the ValueSet.

Does anyone have an idea how to link my wounds to each other?

Hi @Mareike Przysucha Here is an example construction linking a concern to a problem that is an entry in another section: https://cdasearch.hl7.org/examples/view/Health%20Concerns/Health%20Concerns%20Link%20to%20Problems%20Section This uses the generic REFR and an an Act with the same ID as the target (here an observation ). I was a bit surprised to see the same id reused in two different acts, but in this context it is clear that this act is just a reference (like externalAct in the example below). You could use the act.code of the "referencing act" to indicate more details on this relationship.
Here is another example, this time using reference and externalAct http://cdasearch.hl7.org/examples/view/6fa91e8f-225d-4f4c-a18b-dbc7193b10b0 Usually, the externalAct would point to something in another document.

Any other suggestions, @Giorgio Cangioli ?

Thanks, @Christof Gessner. So I think I will choose REFR.
